Description

用作因特网电话的增强型无线电电话及实现电话功能的方法 Internet telephony is used as enhanced radio telephone and method for telephony functions

发明背景本发明涉及IP电话,更具体地说涉及用于IP电话通信的一种改进型终端用户接口。 Background of the Invention The present invention relates to IP telephony, and more particularly relates to an improved end-user interface for the IP telephone communication.

今天,对传统的电话来说因特网电话是一种新的挑战,因为通过全球因特网打长图电话价格相对较低。 Today, the traditional telephone for Internet telephony is a new challenge, because playing a long view of the global Internet through phone prices are relatively low. 另外,虽然现在的因特网电话系统提供的服务质量相对较差,但是未来的改进将毫无疑问地提供不比传统系统差的信号质量。 In addition, although the quality of service provided by the Internet telephone system is relatively poor, but future improvements will no doubt provide a better than traditional systems of poor signal quality.

现有的IP电话主要包括一台多媒体个人计算机(PC),该计算机中运行的电话程序将终端用户的声音信号转换成适当格式的数字信号,在计算机网络(例如全球因特网)上传输,反之亦然。 Conventional IP telephone includes a multimedia personal computer (PC), telephone computer programs running on the end user's audio signal converted into the appropriate format of the digital signals, transmitted over a computer network (e.g., the global Internet), and vice versa However. 这种多媒体PC通常包括一块声卡,声卡上有麦克风和喇叭用于输入输出,并通过适当的网络接口访问计算机网络,这种接口有公共交换电话网(PSTN)、无线网、公用或专用数据网。 Such media typically comprise a PC sound card, sound card with a microphone and speaker for inputting and outputting, by appropriate network interface to access a computer network, the interface has a Public Switched Telephone Network (PSTN), wireless network, a public or private data network . 电话程序将终端用户的语音信号进行压缩和解压缩,以便降低对计算机网络的传输带宽要求。 The end user's telephone program speech signal compression and decompression to reduce the bandwidth requirements for computer network. 因此,语音编码和解码通常是在多媒体PC的中央处理单元(CPU)里进行的。 Thus, speech coding and decoding is typically carried out in the multimedia PC central processing unit (CPU) inside. 具体的语音编码类型(例如GSM[全球数字移动通信系统]、D-AMPS[数字高级移动电话服务]等等)取决于特定应用的比特率和语音质量要求。 The specific type of speech coding (e.g. the GSM [Global digital mobile communication system], D-AMPS [Digital Advanced Mobile Phone Service], etc.) depends on the bit rate and speech quality requirements for a particular application. 压缩过的声音信号采用适当的UDP(用户数据报协议)/IP网络协议在计算机网络中传输,这在本领域里众所周知。 Compressed audio signal using an appropriate UDP (User Datagram Protocol) / IP network transport protocols in computer networks, which are well known in the art. 至于语音编码和译码,常常是由多媒体PC上运行的电话程序来管理计算机网络协议的。 As for speech coding and decoding, often by telephone multimedia program running on a PC to manage computer network protocols.

除了以上优点外,现在的IP电话跟传统电话相比有几个缺点。 In addition to these advantages, the current IP phone compared with traditional phone has several drawbacks. 例如,普通的语音编码和解码算法需要高性能的PC,包括相对较快的CPU。 For example, common speech coding and decoding algorithms require high performance of the PC, including relatively fast CPU. 另外,传统的IP电话应用程序需要另外的声音处理装置,例如声卡和麦克风,这常常不包括在标准消费的个人计算机包装里。 In addition, the traditional IP telephony applications require additional audio processing device, such as a sound card and a microphone, which often does not include the personal computer packed in a standard consumer's.

因此,传统的IP电话需要一台高端个人计算机,跟传统电话相比,这种高端计算机价格高,功耗大,体积也大。 Therefore, the traditional IP phones require a high-end personal computer, compared with the traditional telephone, high-end computer that price, power consumption, size large. 另外,PC通常处于关机状态,需要相对较长的启动时间,很不方便。 In addition, PC is usually turned off, take a relatively long start-up time, very convenient. 而且,即使是配置齐全的PC通常也没有舒服的终端用户电话手机,PC的麦克风和喇叭远,会产生回声。 Moreover, even the fully equipped PC usually do not have a comfortable end-user telephone handset, PC's microphone and speakers far, will produce an echo. 因此,确实需要改进IP电话。 Therefore, we do need to improve the IP phone.

发明简述本发明通过提供一种增强型无线电电话来满足上述需要和其它需要,它可以跟PC相连,成为性能显著改善的IP电话。 SUMMARY The present invention provides an enhanced radio telephone to meet the above and other needs, which can be connected with the PC, be significantly improved performance of the IP phone. 跟普通无线电电话比较,普通电话中的语音编码数字接口只跟无线电电路相连,用于无线通信(例如通过蜂窝式无线电系统),而这种增强型无线电电话还能通过外部连接收发数字编码语音信号。 Comparison with a general radio telephone, an ordinary telephone speech encoding digital interface only with the radio circuit is connected to a wireless communication (e.g. via a cellular radio system), the enhanced radio telephone which can send and receive through the external connector digital coded speech signals . 因此,这种增强型无线电电话可以有选择性地作为普通无线电电话或者改进型IP电话来工作。 Thus, the enhanced radio telephone which can be selectively modified as a regular IP telephone or radio telephone to operate.

这种增强型无线电电话包括一个内部语音编码器,用于降低功耗,并允许将这种增强型无线电电话跟性能较差的PC一起工作以实现IP电话功能。 The enhanced radio telephone includes an internal speech coder, reducing power consumption, and allow such enhanced radio telephone to work with poor performance PC for IP telephone function. 因此这种增强型无线电电话提供了一种低价IP电话的解决方案,跟普通IP电话系统相比它能够减少语音延迟。 This enhanced radio telephone therefore provides a solution to a low-cost IP phone compared with ordinary IP telephone system that can reduce voice delay. 此外,用这种增强型无线电电话手机进行语音对话非常方便,它还解决了前面提到的普通IP电话的回声问题。 In addition, a voice conversation with this enhanced radio telephone handset is very convenient, it also solves the echo problem common IP phones mentioned earlier.

在实施方案实例里,这种增强型无线电手机通过电缆跟运行快速高效电话程序的PC的串口或并口相连。 In example embodiments, this kind of enhanced wireless phone is connected by a cable running fast and efficient telephone program with the PC's serial port or parallel port. 在其它的实施方案里,在增强型无线电电话和PC之间采用一种无线红外(IR)或者短距离无线电连接。 In other embodiments, the use of wireless infrared (IR) or short range radio connection between the enhanced radio telephone and the PC. 编码和压缩过的数字语音信号在增强型无线电电话和PC之间来回传递,PC实现编码语音信号和适当的计算机网络协议之间的转换。 Coding and compressed digital speech signals transmitted back and forth between the enhanced radio telephone and the PC, PC to switch between the coded speech signals and an appropriate computer network protocol. 由于PC不必进行语音编码和解码,因此PC可以是例如一台低端台式计算机、一台膝上型/笔记本计算机甚至是一台掌上型计算机。 Since the PC does not have to be the voice encoding and decoding, so the PC can be for example a low-end desktop computers, a laptop / notebook computer or even a palmtop computer.

标准PC的串口或并口连接足以在增强型无线电电话和PC之间进行双向数字语音和控制信令传递。 Standard PC serial or parallel port connection is sufficient for the bidirectional digital transmission of voice and control signaling between the enhanced radio telephone and the PC. 本发明中的IP电话控制或者是始于PC或者是始于增强型无线电电话。 In the present invention, IP telephone control is started or the PC is started or enhanced radio telephone. 另外,这种增强型无线电电话可以用手动方式(例如通过无线电手机上的一个按钮)或者PC控制的自动方式(例如通过PC上运行的电话程序选项)在普通无线电(例如蜂窝式)电话和IP电话之间切换。 Furthermore, the enhanced radio telephone which can be used manually (e.g., via a button on the radio handset) or automatically controlled by a PC mode (e.g., by telephone program on a PC running options) (e.g., cellular) in a general radio telephone and IP switch between calls. 更进一步,既可以用PC电话程序也可以用增强型无线电电话上的小键盘来始发呼叫。 Furthermore, both can also originate calls using the keypad on the enhanced radio telephone with PC telephony program.

在另外的实施方案里,这种增强型无线电电话还用于无线数据通信以便传递IP语音。 In additional embodiments, the enhanced radio telephone which is also used for wireless data communication in order to deliver voice over IP. 换句话说,编码语音从增强型无线电电话传递到PC里,在这台PC里将编码语音转换成适当的UDP/IP网络协议格式,得到的IP语音又传回这架增强型无线电电话,从而通过无线电网络接口传递给一个计算机网络。 In other words, coded speech is transmitted from the enhanced radio telephone to the PC where the PC in this encoded voice into an appropriate UDP / IP network protocol format, and obtained the IP voice return plane enhanced radio telephone, whereby transferred through a radio network interface to a computer network. 在这一实施方案实例里,IP数据传输或者是用这一增强型无线电电话的单独连接,或者是用传递编码语音和控制信令的同一连接来进行的。 In this embodiment, in instances, the IP is connected to data transmission or the enhanced radio telephone alone, or with the same connection for the transmission of encoded speech and control signaling. PC串口足以传递数字语音、控制信令和IP数据。 PC serial port is sufficient to transfer digital speech, control signaling and IP data.

简而言之,本发明提供一种改进型IP电话,跟普通IP电话系统比起来它更加方便、经济,效率更高。 In short, the present invention provides an improved IP telephony, it is more convenient with the ordinary IP telephone system compared to higher economic efficiency. 下面将参考附图更加详细地介绍本发明的这些特征和其它特征。 It will now be described with reference to the accompanying drawings These features and other features of the present invention in more detail. 本领域的技术人员应当明白这里的实施方案只是为了说明本发明,其中的实施方案还可以有各种等价形式。 Those skilled in the art will appreciate that embodiments described herein is for the purpose of the present invention, wherein the various embodiments may also be equivalents.

图2是本发明中IP电话系统的框图。 FIG 2 is a block diagram of the present invention, the IP telephone system.

图3和4都是本发明中IP电话系统的其它选择。 FIGS. 3 and 4 of the present invention are selected other IP telephone system.

发明详述图1说明的是现有技术里的IP电话系统100。 DETAILED DESCRIPTION OF THE INVENTION FIG 1 is described in the prior art IP telephony system 100. 如图所示,这一普通电话系统100包括一台高性能的PC110和一个网络接口120。 As illustrated, the ordinary telephone system includes a high-performance 100 and a network interface 120 PC110. 这台高性能的PC110包括一个喇叭105、一块声卡125、一个麦克风115、一个CPU135和一个输入/输出口145。 This high-performance PC110 105 comprises a speaker, a sound card 125, a microphone 115, a CPU135, and an input / output port 145. 在图中,麦克风115的输出端跟声卡125的输入端相连,声卡125的输出端跟喇叭105的输入端相连。 In the drawing, the output of microphone 115 is coupled to the input 125 is connected to the sound card, sound card 125 is connected to an output terminal coupled to the input 105 of the horn. 声卡125的一个输入/输出口跟CPU135的第一个输入/输出口相连,CPU135的第二个输入/输出口跟PC的输入/输出口145相连。 A sound input / output port 125 with a CPU135 first input / output port is connected, the CPU135 is connected to the second input / output port of the PC with the input / output port 145. PC的输入/输出口145自己又跟网络接口120的第一个输入/输出口相连,网络接口120的第二个输入/输出口则跟网络130相连。 PC input / output port 145 any connection with their network interface 120 of the first input / output port is connected, the network interface of the second input / output port 120 is connected with the network 130. 网络130可以是,例如,全球因特网或者公众或者个人组织运营的内部网。 The network 130 may be, for example, the global Internet or intranet public organization or individual operations. 因此,应当将术语“IP”理解为同时包括因特网协议和内部网协议。 Thus, the term "IP" should be understood to include both intranet and Internet Protocol protocol.

PC110的近端用户通过例如启动PC110上的电话程序来启动IP电话呼叫。 PC110 near-end user via the telephone, for example, to start the program on the IP phone call to initiate PC110. 在对话中,近端用户对着麦克风115说话,声卡125将麦克风115收到的音频信号数字化。 In the dialogue, the near end user to speak into the microphone 115, an audio signal will sound 125 115 receive digital microphone. 声卡125将数字信号输送给CPU135。 Card 125 to the digital signal conveyed CPU135. 运行电话程序的CPU135利用合适的语音编码算法(例如GSM、D-AMPS等等)对数字语音信号进行压缩和编码,并用合适的UDP/IP网络协议将编码语音转换成适合于在网络130里传输的格式。 CPU135 run telephone program using a suitable speech coding algorithms (e.g., GSM, D-AMPS, etc.) on the digital speech signal is compressed and encoded, and with the appropriate UDP / IP network protocol converts the encoded voice to be suitable at 130 in the transmission network format. CPU135通过PC的输入/输出口145将得到的IP数据发送给网络接口120,网络接口则将它传递到网络130里,并传递给远端用户。 CPU135 transmits IP data through the input / output port of the PC 145 to the network interface 120 obtained, then it is passed to the network interface 130 in the network, and transmitted to the remote user.

反过来,网络接口120从网络130接收远端用户的IP语音信号,并通过PC的输入/输出口145输送到PC110里。 In turn, the network interface 120 receives the distal end of the delivery outlet user IP network 130 a voice signal, input from the PC through / PC110 145 to the inside. CPU135收到IP格式的远端数据以后,将它转换为相应的编码远端语音信号。 After the distal end of the CPU135 receives IP data format, converts it to corresponding coded far-end speech signal. CPU135用合适的算法将编码远端语音信号解码,产生数字声音数据并传送给声卡125。 CPU135 the encoded far-end voice signal decoding with an appropriate algorithm to produce digital sound data to the sound card 125 and transmitted. 声卡125将数字远端声音数据转换成对应的模拟信号,传递给喇叭105让近端用户听。 The distal end of the sound card 125 converts the digital audio data into a corresponding analog signal, transmitted to the speaker 105 allows the user to listen to the proximal end.

在本领域里众所周知,网络接口120可以跟许多系统中的任意一个连接以便接入网络130。 Is well known in the art, the network interface 120 may be any of a number system with a connection to the access network 130. 例如网络接口120可以跟适当的公共交换电话网(PSTN)、无线电系统、公用或专用数据网相连。 The network interface 120 may, for example, a radio system, public or private data networks connected with the appropriate public switched telephone network (PSTN). 因此,随着链路类型的不同,PC110和网络接口120之间的链路可以使用任何合适的数字协议。 Accordingly, as different types of links, the link between the PC 110 and the network interface 120 may use any suitable digital protocol. 如果这条链路是一个模拟PSTN,网络接口120就用普通的调制解调器将PC110输出的数字编码信息转换成适合于普通电话线传输的模拟信号。 If this link is an analog PSTN, the network interface 120 to a conventional modem PC110 digitally encoded information into an output suitable for regular phone lines to an analog signal. 如果这条链路是一个数字电话网络,网络接口120就将PC110输出的数字信息转换成这一电话网络(例如ISDN)的数字协议格式。 If this link is a digital telephone network, the network interface 120 will digital information output is converted into the PC110 telephone network (e.g., ISDN) digital protocol format. 当这条链路是一个无线电系统时,网络接口120就用一个合适的收发信机收发信号并进行调制和解调。 When this link is a radio system, the network interface 120 to use a suitable transceiver for transmitting and receiving signals, and modulation and demodulation. 当这条链路是一个公用或专用数据网时,网络接口120就将来自PC110的数字编码信息转换成适合于这一公用或专用网络的格式。 When this link is a public or private data network, the network interface 120 will convert the digital information from the encoding PC110 is to be suitable for the public or private network format. 将网络接口120集成到PC110甚至CPU135中将更好。 The network interface 120 will be integrated into the PC110 CPU135 even better.

如上所述,虽然图1中的系统足以应付特定的应用,但它有几个明显的缺点。 As described above, although the system of FIG. 1 sufficient for certain applications, but it has several distinct disadvantages. 例如,减少延迟和提高信号质量必需的高级语音编码和解码算法要求CPU135运算速度相当快。 For example, reducing advanced speech coding and decoding algorithms and delay requirements necessary to improve the signal quality calculation CPU135 very fast. 另外,声卡125和麦克风115都是附件,标准消费PC包装中常常没有这些东西。 In addition, a sound card and a microphone 115 are 125 accessory, the standard consumer PC package often do not have these things. 而且用于语音编码/解码和UDP/IP转换的相对复杂的电话程序很可能非常昂贵,还可能需要很大的计算机存储器空间。 And a speech coding / decoding and UDP / IP conversion is relatively sophisticated telephone program can be very expensive, may require significant computer memory space. 本发明指出,可以改进平常只用于无线电(例如蜂窝式)通信的无线电电话,让它跟PC里的电话程序一起工作,在PC以外完成计算量很大的语音编码和解码,从而可以非常经济地实现IP电话而不需要高端计算机。 Noted that the present invention may be modified usually only for a radio (e.g., cellular) radio telephone communications, it work with telephone program in the PC, to complete a large amount of calculation in encoding and decoding of speech outside the PC, it can be very economical to implement IP telephony without the need for high-end computers.

图2是本发明中IP电话系统200的示意图。 FIG 2 is a schematic diagram of an IP telephone system 200 according to the present invention. 如图所示,这一改进了的IP电话系统200包括一个增强型无线电话250、一台PC210和一个网络接口120。 As shown, the improved IP telephony system 200 includes an enhanced wireless telephone 250, a network interface 120, and a PC210. 增强了的无线电话250包括喇叭205(例如无线手机里的耳机)、语音解压缩器225、天线255、射频收发信机265、数字接口275、外部连接245、语音压缩器235和麦克风215(例如无线手机里的话筒)。 Enhanced wireless telephone 250 includes a speaker 205 (e.g., a wireless phone headset), a speech decompressor 225, an antenna 255, a radio frequency transceiver 265, a digital interface 275, an external connection 245, a speech compressor 235 and a microphone 215 (e.g. wireless phone's microphone).
